Codes:
Comments.php

<?php
if(isset($_GET['logout'])){   
   
    //Simple exit message
    $fp = fopen("log.html", 'a'); {
    if($row['userlevel'] ==9);
    fwrite($fp, "<div class='msgln'><i>User <span style='background: url(/admin/images/backround6.gif)'>". $row['username'] ."</span> has left the chat session.</i><br></div>");
}
 
    if($row['userlevel'] == 8); {
    fwrite($fp, "<div class='msgln'><i>User <span style='background: url(/admin/images/backround9.gif)'>". $row['username'] ."</span> has left the chat session.</i><br></div>");
}
 
    if($row['userlevel'] == 1); {
    fwrite($fp, "<div class='msgln'><i>User ". $row['username'] ." has left the chat session.</i><br></div>");
}
    fclose($fp);
   
    session_destroy();
    header("Location: index.php"); //Redirect the user
}
?>

Post.php:

<?php
session_start();
    $text = $_POST['text'];
   
    $fp = fopen("log.html", 'a');
    if($user->is_Admin()):
    fwrite($fp, "<div class='msgln'>(".date("g:i A").") <b><span style='background: url(/admin/images/backround6.gif)'>". $row['username'] ."</span></b>: ".stripslashes(htmlspecialchars($text))."<br></div>");
    endif;
    fwrite($fp, "<div class='msgln'>(".date("g:i A").") <b>". $row['username'] ."</b>: ".stripslashes(htmlspecialchars($text))."<br></div>");
    fclose($fp);
?>

After checkin for admin shouldn't it be else?

 

[Li1M0ST3Rz]

else or elseif?

 

[Donkjam]

I'm not too good with PHP but try

<?php
session_start();
    $text = $_POST['text'];
   
    $fp = fopen("log.html", 'a');
    if($user->is_Admin()):
    fwrite($fp, "<div class='msgln'>(".date("g:i A").") <b><span style='background: url(/admin/images/backround6.gif)'>". $row['username'] ."</span></b>: ".stripslashes(htmlspecialchars($text))."<br></div>");
    Else
    fwrite($fp, "<div class='msgln'>(".date("g:i A").") <b>". $row['username'] ."</b>: ".stripslashes(htmlspecialchars($text))."<br>
</div>");
    fclose($fp);
Endif;
?>

Not sure if needs else;
